Fluidic seal module

Delivery of liquids sensitive to contact with air or moisture

Fluidic seal module enables to deliver liquids sensitive to contact with air or moisture. The module can be applied for liquids which tend to react or crystallize in contact with gases such as oxygen or water vapor. It is recommended to discuss the use of a fluidic seal module with the pump manufacturer.
The fluidic seal module prevents both the liquid from leaking out of the shaft seal area and the surrounding gases and moisture from penetrating into the pump. A fluid chamber is formed between the shaft sealing of the pump and an additional sealing. This fluid chamber is filled with a sealing liquid which assures the sealing function. The sealing liquid has to be compatible with the delivered liquid and should be individually selected for each application. By this measure contact with air or moisture can be avoided.
